Key standards
Visual physical commonsense (V-PC)
- A canonical U-tine tuning fork is struck and rings clearly during the clip.
- Fingers visibly touch the prongs of the vibrating tuning fork.
Audio physical commonsense (A-PC)
- A clear ring at a stable fundamental pitch is audible from the fork.
- The ring decays to silence almost instantly once the fingers contact the prongs, with no residual tone.
Cross-modal physical commonsense (AV-PC)
- The ring onset in the audio aligns in time with the visible strike of the tuning fork.
- The abrupt end of the ring coincides in time with the visible moment the fingers contact the prongs.
